Large-scale learner corpora collected from online language learning platforms, such as the EF-Cambridge Open Language Database (EFCAMDAT), provide opportunities to analyze learner data at an unprecedented scale. However, interpreting the learner language in such corpora requires a precise understanding of tasks: How does the prompt and input of a…

The incidence of nativelikeness in adult second language acquisition is a controversial issue in SLA research. Although some researchers claim that any learner, regardless of age of acquisition, can attain nativelike levels of second language (L2) proficiency, others hold that attainment of nativelike proficiency is, in principle, impossible. The…

A model of speech perception and production is suggested here which attempts to account for different rates of acquisition of perceptual and productive skill in the second language without assuming the existence of two separate second language grammars. (Author/KM)

Investigated how well nonnative speakers (NNSs) could modify their output toward comprehensibility when interacting with native speakers (NSs) and NNSs, noting how often modified comprehensible output (MCO) was other- or self-initiated. Picture-dictation and opinion-exchange task data indicated that most repairs were self-initiated. NNS-NNS…
